After introducing the BLU Pure XL last month and marketing it to T-Mobile customers, BLU is back again today with two more Android phones that it’s aiming at T-Mo users.

The BLU Studio Energy 2 and Energy X are all about battery life, with the former offering a 5000mAh battery and the latter packing a 4000mAh battery. BLU claims that both will get you 3 days of use on a single charge. One downside to the batteries is that they’re both non-removable, but most of the mobile industry is trending that direction, so it’s not totally surprising to see on BLU’s new phones.

Here are the full spec lists for both of BLU’s new pieces of kit:

Studio Energy 2

• 5-inch 1280×720 Super AMOLED display
• 1.3GHz quad-core MediaTek 6735 processor
• 8-megapixel rear camera with LED flash
• 5-megapixel front camera
• 16GB of storage
• microSD slot
• 1.5GB of RAM
• Dual SIM
• GSM 850/900/1800/1900

• LTE bands 2, 4, 7, and 17
• Non-removable 5000mAh battery
• 144.0 x 71.2 x 10.1mm
• Android 5.0 Lollipop

Energy X

• 5-inch 1280×720 LCD screen
• 1.3GHz quad-core MediaTek 6580 processor
• 8-megapixel rear camera with LED flash
• 2-megapixel front-facing shooter
• 8GB of storage
• microSD slot
• 1GB of RAM
• Dual SIM
• GSM 850/900/1800/1900

• 142.0 x 70.0 x 8.9mm
• Android 5.1 Lollipop

One other detail that’s worth noting is that while BLU is marketing these new phones at T-Mobile and MetroPCS subscribers, the devices don’t support all of T-Mo’s wireless bands. For example, the Studio Energy 2 is missing band 12, which means no Extended Range LTE that reaches farther distances and offers better building penetration, and no Voice over LTE, either. It also doesn’t support T-Mobile’s 1700/2100MHz HSPA, though T-Mobile has been focusing on its refarmed 1900MHz HSPA coverage more as of late. Meanwhile, the Energy X has no LTE at all, though it does at least boast better support for T-Mobile HSPA than its Studio Energy 2 sibling.

If you’re willing to accept those wireless trade-offs, you can snag the Studio Energy 2 and Energy X from Amazon starting today. The Studio Energy 2 is priced at $179.99 unlocked, while the Energy X is $109.00 unlocked.
